Studies on the pathogenic potential of heterodera zeae and pratylenchus zeae on maize in Haryana

In green-house experiments, both Heterodera zeae and Pratylenchus zeae, either singly or in combination did not prove pathogenic to maize. The pathogenic potential of either H. zeae or P. zeae was not discernible in different soil types. Soil texture, however, influenced the nematode multiplication. Lighter soils favoured higher multiplication for both the nematode species. P. zeae did not interact with Fusarium pallidoroseum. H. zeae, however, favoured fungal damage when inoculated one week after the fungus.
